The hit programme, which ran for a decade on Channel 4, will return later this year after C5 and producers Endemol finally signed off a deal for the series yesterday.
A new "all-star celebrity" version of the show will launch in the late summer followed by a brand new series featuring members of the public in the autumn. The programme will continue to be filmed at Elstree Film Studios and produced by Endemol UK's production arm Initial.
Channel 5's director of programmes Jeff Ford said: "We're hugely excited to have secured the return of Big Brother for Channel 5 which will form a key part of this year's schedule.
"The series has previously captivated a decade of television viewers and we aim to bring Channel 5's energy, optimism and vibrancy to the series."
Endemol chief executive Tim Hincks said: "Big Brother has a passionate and loyal fanbase in the UK and I'm delighted it has found a new home on Channel 5. Ten years on it's as potent and cutting-edge as ever and it's still one of the only truly multiplatform entertainment brands."
Steve Gowans, Channel 5's head of factual entertainment, will oversee the project with Initial's Nick Samwell-Smith and Laurence Jones.
Davina McCall has previously confirmed that she will not return as the host. It has not been revealed whether 'The Voice Of Big Brother' Marcus Bentley will continue with his voiceover role on Channel 5.
